Help with indoor antenna.

Sorry, I'm sure you get a ton of questions about this, I wanted to ask some specific questions. I have been struggling to capture the same FM stations in my home I get in my car. I have cobbled together a combo FM/AM antenna and mounted it in my Attic which is fairly high (3 story house). The antenna uses rabbit ears for the FM section, and I built a wire loop for the AM section both connected to opposite ends of a PVC shaft. AM Signal is non-existant, FM is ok but not as good as my car. Clearly the rabbit ears could be shot, but I am also questioning the connectors/wire I used to my receiver. For FM I used an old balun and ran coax the 70' to my receiver. Should I have used 2 lead antenna "flat wire"? How about on the AM side, should I have used antenna flat wire there also and ran that the 70' to the receivers? I feel I should be getting close, but am still not there yet. Oh one more question, how critical is the expanded length of the rabbit ears? Should I just expand them the maximum?

Thanks for any and all help!!!

^This is wrong. FM covers certain frequencies, and needs antenna element that has certain length. My Attic FM antenna has 4 (FOUR) foot elements on each side. Some fancy ELECTRONIC controlled antennas attempt to shrink this requirement but with passive antennas, there is no way to finagle this length thing. AM doesn't require much but if you have difficulty with some stations, a TUNED AM antenna will zero in that station.
